Adblue

AdBlue is an easy-pour solution that reduces NOX emissions by up to 80%. For most modern diesels, failing to refill AdBlue solution when required will result in your car not starting. It is stored within a separate tank in your car or van but unlike petrol or diesel it does not get injected into the engine, instead it is fed into part of the vehicles exhaust sytem which then converts the harmful NOX emissions into harmless nitrogren and water.
